Types of transformations

Reflection across the x axis

Reflection across the y axis

Translation If the shape is moved 6 spaces right and 4 spaces up This co This could look like this on your STAAR test x + 6, y + 4

A The following shape is going to be translated 8 spaces right and 5 spaces down. Where will coordinate A’ be located? A’ (5, -1)

Dilation with a scale factor of 3 -1,1 -3,3

Find the scale factor that was used 2.4m 7.2m 2.4 ? = 7.2 3

Find the scale factor that was used 8m 16m 16 ? = 8 0.5

Find the scale factor that was used Triangle ABC is at coordinates: A(3, 0) B(1, 4) and C(5, 0) Triangle A’B’C’ is at coordinates: A’(4.5, 0) B’(1.5, 6) and C’(7.5,0) What scale factor was used to make the dilated triangle? 3 ? = 4.51 ? = 1.54 ? = 65 ? = All of the answers have to be the same number So the answer is…… 1.5

X Y III IIIIV I (+, +)(-, +) (-, -)(+, -) The spot where the x axis and the y axis meet is called the origin Origin The 4 regions are called quadrants

Reflection across the ____ axis

Translation If the shape is moved ____ spaces right and ______ spaces up

A The following shape is going to be translated ____ spaces right and ____ spaces down. Where will coordinate A’ be located?

Dilation with a scale factor of ____

Find the scale factor that was used

Triangle ABC is at coordinates: A(3, 0) B(1, 4) and C(5, 0) Triangle A’B’C’ is at coordinates: A’(4.5, 0) B’(1.5, 6) and C’(7.5,0) What scale factor was used to make the dilated triangle? ? = All of the answers have to be the ______ number So the answer is……
